SUMMARY: Which dump is on tape

My original question:

  Aharon> a way to get vrestore to tell me the time, date, and file
  Aharon> system that is backed up in the dump file.

The solution (from Winfried Huber <win_at_tukan.ffb.eunet.de>)


run "vrestore -i". You will get something like (note the date) ...

tukan#366# vrestore -i
vrestore: Date of the vdump save-set: Sun Jan 28 20:53:15 1996
(/)

... next do "ls", and you will get something like ...

(/) ls

.:
                #.mrg..DXsession .Xauthority
                          .cshrc .cshrc.bak
(/)

... now you have to guess which file system got dumped here. It's
painful, but true: The date of the dump is recorded in the header, but
not the name of the file system or path that is dumped here. I
invested some time to analyze a dump tape to verify this.

But there is a easy workaround for this: Simply generate a uniqe
(empty) file describing the node name and the path in every mount
point, e.g. for /usr/users on host tukan something like
"tukan_usr_users", and your problem is solved, for future dumps...

But note that vdump is not restricted to dump entire file systems, you
may restrict vdump to a directory tree using the "-D" switch.
